Salt Lake City, UT—Attorneys for an environmental activist convicted of federal charges for derailing an oil and gas lease auction on public land are appealing his conviction and two-year prison sentence.

Tim DeChristopher’s attorneys filed a notice of appeal Monday in Salt Lake City’s U.S. District Court. The document says an appeal will be filed with the 10th Circuit Court of Appeals in Denver. DeChristopher was convicted in March of two felony counts for interfering with and making false representations at a government auction.

He ran up $1.8 million in false bids on parcels near Utah’ Arches and Canyonlands national parks. DeChristopher maintains his bids were an act of civil disobedience. Last week, a federal judge sentenced him to two years prison, three years of probation and a $10,000 fine. Source
